slide 2: History of Screen Printing Screen printing first appeared in a recognizable form in China during the Song Dynasty 960–1279 AD. It was then adapted by other Asian countries like Japan and was furthered by creating newer methods. Screen printing was largely introduced to Western Europe from Asia sometime in the late 18th century but did not gain large acceptance or use in Europe until silk mesh was more available for trade from the east and a profitable outlet for the medium discovered. Early in the 1910s several printers experimenting with photo-reactive chemicals used the well- known actinic light–activated cross linking or hardening traits of potassium sodium or ammonium chromate and dichromate chemicals with glues and gelatin compounds. Roy Beck Charles Peter and Edward Owens studied and experimented with chromic acid salt sensitized emulsions for photo-reactive stencils. This trio of developers would prove to revolutionize the commercial screen printing industry by introducing photo-imaged stencils to the industry though the acceptance of this method would take many years. Commercial screen printing now uses sensitizers far safer and less toxic than bichromates. Currently there are large selections of pre-sensitized and "user mixed" sensitized emulsion chemicals for creating photo-reactive stencils. A group of artists who later formed the National Serigraphic Society including WPA artist Anthony Velonis coined the word Serigraphy in the 1930s to differentiate the artistic application of screen printing from the industrial use of the process."Serigraphy" is a compound word formed from Latin "sēricum" silk and Greek "graphein" to write or draw. The Printers National Environmental Assistance Center says "Screenprinting is arguably the most versatile of all printing processes. Since rudimentary screenprinting materials are so affordable and readily available it has been used frequently in underground settings and subcultures and the non- professional look of such DIY culture screenprints have become a significant cultural aesthetic seen on movie posters record album covers flyers shirts commercial fonts in advertising in artwork and elsewhere. 1960s to present Credit is generally given to the artist Andy Warhol for popularising screen printing as an artistic technique identified as serigraphy in the United States. Warhol was supported in his production by master Screen Printer Michel Caza a founding member of Fespa and is particularly identified with his 1962 depiction of actress Marilyn Monroe known as the Marilyn Diptych screen printed in garish colours. Sister Mary Corita Kent gained international fame for her vibrant serigraphs during the 1960s and 1970s. Her works were rainbow colored contained words that were both political and fostered peace and love and caring. American entrepreneur artist and inventor Michael Vasilantone started to use develop and sell a rotatable multicolour garment screen printing machine in 1960. Vasilantone later filed for patent on his invention in 1967 granted number 3427964 on February 18 1969. The original machine was manufactured to print logos and team information on bowling garments but soon directed to the new fad of printing on T-shirts. The Vasilantone patent was licensed by multiple manufacturers the resulting production and boom in printed T-shirts made this garment screen printing machine
slide 3: popular. Screen printing on garments currently accounts for over half of the screen printing activity in the United States. Graphic screenprinting is widely used today to create mass or large batch produced graphics such as posters or display stands. Full colour prints can be created by printing in CMYK cyan magenta yellow and black key. Screen printing lends itself well to printing on canvas. Andy Warhol Arthur Okamura Robert Rauschenberg Roy Lichtenstein Harry Gottlieb and many other artists have used screen printing as an expression of creativity and artistic vision. Printing Techniques A screen is made of a piece of mesh stretched over a frame. The mesh could be made of a synthetic polymer such as nylon and a finer and smaller aperture for the mesh would be utilized for a design that requires a higher and more delicate degree of detail. For the mesh to be effective it must be mounted on a frame and it must be under tension. The frame which holds the mesh could be made of diverse materials such as wood or aluminum depending on the sophistication of the machine or the artisan procedure. The tension of the mesh may be checked by using a tensiometer a common unit for the measurement of the tension of the mesh is Newton per centimeter N/cm. A stencil is formed by blocking off parts of the screen in the negative image of the design to be printed that is the open spaces are where the ink will appear on the substrate. Before printing occurs the frame and screen must undergo the pre-press process in which an emulsion is scooped across the mesh and the exposure unit burns away the unnecessary emulsion leaving behind a clean area in the mesh with the identical shape as the desired image. The surface to be printed commonly referred to as a pallet is coated with a wide pallet tape. This serves to protect the pallet from any unwanted ink leaking through the screen and potentially staining the pallet or transferring unwanted ink onto the next substrate. Next the screen and frame are lined with a tape. The type of tape used in for this purpose often depends upon the ink that is to be printed onto the substrate. These aggressive tapes are generally used for UV and water-based inks due to the inks lower viscosities. The last process in the pre-press is blocking out any unwanted pin-holes in the emulsion. If these holes are left in the emulsion the ink will continue through and leave unwanted marks. To block out these holes materials such as tapes speciality emulsions and block-out pens may be used effectively. The screen is placed atop a substrate. Ink is placed on top of the screen and a floodbar is used to push the ink through the holes in the mesh. The operator begins with the fill bar at the rear of the screen and behind a reservoir of ink. The operator lifts the screen to prevent contact with the substrate and then using a slight amount of downward force pulls the fill bar to the front of the screen. This effectively fills the mesh openings with ink and moves the ink reservoir to the front of the screen. The operator then uses a squeegee rubber blade to move the mesh down to the substrate and pushes the squeegee to the rear of the screen. The ink that is in the mesh opening is pumped or squeezed by capillary action to the substrate in a controlled and prescribed amount i.e. the wet ink deposit is proportional to the thickness of the mesh and or stencil. As the squeegee moves toward the rear of the screen the tension of the mesh pulls the mesh up away from the substrate called snap-off leaving the ink upon the substrate surface. There are three common types of screen printing presses. The flat-bed cylinder rotary.
slide 4: Textile items printed with multicoloured designs often use a wet on wet technique or colours dried while on the press while graphic items are allowed to dry between colours that are then printed with another screen and often in a different colour after the product is re-aligned on the press. Most screens are ready for re-coating at this stage but sometimes screens will have to undergo a further step in the reclaiming process called dehazing. This additional step removes haze or "ghost images" left behind in the screen once the emulsion has been removed. Ghost images tend to faintly outline the open areas of previous stencils hence the name. They are the result of ink residue trapped in the mesh often in the knuckles of the mesh the points where threads cross. While the public thinks of garments in conjunction with screen printing the technique is used on tens of thousands of items including decals clock and watch faces balloons and many other products. The technique has even been adapted for more advanced uses such as laying down conductors and resistors in multi-layer circuits using thin ceramic layers as the substrate.
